Description

Top, silo storehouse steel pipe truss support system and construction method thereof
Affiliated technical field
The invention belongs to structural engineering technical field, relate to top, a kind of silo storehouse steel pipe truss support system.
Background technology
Along with the continuous increase of coal demand and the raising to environmental protection requirement, a kind of reserves are large, floor space is little, and the major diameter coal bunker that meets strategy of sustainable development requirement is widely applied at Coalmine Coal Preparation Plant and coal storage system.In coal bunker engineering construction, roof construction construction in storehouse is one of key link in work progress, and the design of storehouse roof construction support system and checking computations are particularly important to Cang Ding construction.The construction method of tradition support system is set up for full hall frame, and still along with the progress of construction technology, full hall frame formwork system is because its expense is high, speed is replaced by some novel Construction Supporting Systems slowly gradually.What first promote is that fastener type steel pipe trussed construction and center derrick combination form replace traditional full hall scaffold, derrick and steel pipe truss structures are connected as a single entity as the support system of deck construction, derrick is along with the lifting of slip form platform is progressively set up, drag-line is set on derrick height to be socketed support body, guarantee its stability, it is solid that derrick is set up ground, guarantees that derrick support body does not sink.After barrel slding form operation finishes, then carry out being connected of derrick and steel pipe truss system, generally, promotional value is very high.On the basis of this support system, there is again shaped steel central frame radiation support platform, this structure is fastener type steel pipe truss and steel truss beam combination structure, mainly to utilize steel truss beam, as horizontal stiffness stiffening girder, steel pipe truss is retrained to reinforcement, the problem of the steel pipe truss structures supporting capacity deficiency causing because of the excessive generation excessive deformation of load in control use procedure, these two kinds of method constructions are convenient, safe and reliable, work efficiency is high, cost is low, sets up the link of support but still do not break away from from silo bottom.In order thoroughly to change traditional vertical support system into space horizontal struts system, there is again fastener type steel pipe truss support system, after steel pipe truss is fixed by the method constraint of upper Suspension hanger (bar is connected with climbing) and lower support (being supported in barrel inner side), as the support system of Cang Ding construction, thereby improve operating personnel's safety guarantee in construction, the energy reduction of erection time simultaneously, reduced construction cost, and member is reusable, save resource.But current this support system is a kind of structural system that is applicable to diameter and is no more than the silo construction of 21m.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of quick construction, obviously reduction of erection time, simple structure, power transmission is clear and definite and can be used for the horizontal struts system that diameter Silo Cang Ding constructs, and top, the silo storehouse construction method of utilizing this kind of support system to realize is provided simultaneously.Steel pipe truss support system provided by the invention and top, silo storehouse construction method, in silo Cang Ding construction, traditional vertical support system transition is become to space horizontal struts system, simultaneously the energy reduction of erection time, reduce construction cost, and meet structural-load-carrying capacity and the normal requirement using.Technical scheme of the present invention is as follows:
Top, a kind of silo storehouse steel pipe truss support system construction method, comprises the following steps:
1) utilize steel pipe and fastener to set up into the space truss structure of the orthogonal spatial being made up of a series of plane frame, be referred to as steel pipe truss (2), the size of steel pipe truss (2) is determined according to the internal diameter of the barrel of silo (10);
